Seller is a fraud.
Selling fake watches, with fake box and papers.
By law in EU, this is forbidden, and customs confiscated the watch, destroyed it, and almost gave me a fine.
Seller wanted me to return the watch to issue the refund, which is not possible. eBay support also didn't understand and wanted for me to return it for the refund to go through.
Expensive mistake by my side, but eventhough I lost the money, I'm reporting the seller for selling counterfeit goods.
